We reported earlier on the rumored Nokia Lumia 900 (aka Nokia Ace) Windows Phone 7 smart phone. We said that it would basically be the Nokia Lumia 800 only a bit bigger and featuring a LTE modem. The Nokia Lumia 900 is now official and the speculation seems to be correct.

It will be available in either cyan or black colors in the US within the next few months and bound to the AT&T network with "aggressive" pricing. Nokia stated in their conference that it has been working closely with Qualcomm to ensure solid performance on AT&T's LTE network. SIM-free and carrier unlocked phones will also be available; however, it is not clear whether users in the US will be able to purchase them (or if they would need to be imported). Ballmer stated plainly that the "Lumia 900 is a very exciting launch," and that AT&T is critical to the WP7 future. More information on the Nokia Lumia 900 can be found here.

A sexy device it is, but personally I've been burned once by Nokia's other (N)900, so I think I'll stick with Android for the time being.
